If your only definition of progressive is relating to Church teachings regarding sexuality, than I suspect you're right - there will be no surprises with this, or any other Pope, in the near future.
However, Jesuits - even conservative ones - chose to enter the Society of Jesus instead of become diocesan priests for a reason. Something about the charism of that order appealed to Pope Francis, and appeals to many, many people. A lot of people consider their preferrential treatment of the poor, dedication to education, missionary work, and call to be "men and women for others" to be progressive.
It was a surprise that the chosen Pope is from the southern hemisphere. It was a surprise that he chose the name Francis. In just a few hours we've already had two surprises. I figure there might just be SOME additional surprises during his papacy.
